Abstract

A 14-year-old boy with severe combined immunodeficiency presented three times to a medical facility over a period of 4 months with fever and headache that progressed to hydrocephalus and status epilepticus necessitating a medically induced coma.Diagnostic workup including brain biopsy was unrevealing.Unbiased nextgeneration sequencing of the cerebrospinal fluid identified 475 of 3,063,784 sequence reads (0.016%) corresponding to leptospira infection.Clinical assays for leptospirosis were negative.Targeted antimicrobial agents were administered, and the patient was discharged home 32 days later with a status close to his premorbid condition.Polymerase-chain-reaction (PCR) and serologic testing at the Centers for Disease Control and Prevention (CDC) subsequently confirmed evidence of Leptospira santarosai infection.M ore than half the cases of meningoencephalitis remain undiagnosed, despite extensive clinical laboratory testing.[1][2][3][4] Because more than 100 different infectious agents can cause encephalitis, establishing a diagnosis with the use of cultures, serologic tests, and pathogen-specific PCR assays can be difficult.Unbiased next-generation sequencing has the potential to revolutionize our ability to discover emerging pathogens, especially newly identified viruses.[5][6][7][8] However, the usefulness of next-generation sequencing for the diagnosis of infectious diseases in a clinically relevant timeframe is largely unexplored.9 We used unbiased next-generation sequencing to identify a treatable, albeit rare, bacterial cause of meningoencephalitis.In this case, the results of next-generation sequencing contributed directly to a dramatic effect on the patient's care, resulting ultimately in a favorable outcome.

  • NGS was used to diagnose neuroleptospirosis in a critically ill 14-year-old boy with meningoencephalitis.

    “NGS was used for the clinical diagnosis of neuroleptospirosis in a 14-year-old critically ill boy with meningoencephalitis19”

    From Clinical metagenomics (2019) · cites this paper as [19]

  • That case was the first demonstration that mNGS can provide clinically actionable information, because diagnosis led to targeted antibiotics and recovery.

    “this case was the first to demonstrate the utility of metagenomic NGS (mNGS) in providing clinically actionable information, as successful diagnosis prompted appropriate targeted antibiotic treatment and eventual recovery of the patient.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
